This is a list of shootings in the United States that have occurred in 2020. Shootings are incidents involving multiple victims of firearm-related violence. The precise inclusion criteria are disputed, and there is no broadly accepted definition.[2][3]
Gun Violence Archive, a nonprofit research group that tracks shootings and their characteristics in the United States, defines a mass shooting as an incident in which four or more people, excluding the perpetrator(s), are shot in one location at roughly the same time.[4] The Congressional Research Service narrows that definition, limiting it to "public mass shootings", defined by four or more victims killed, excluding any victims who survive.[3] The Washington Post and Mother Jones use similar definitions, with the latter acknowledging that their definition "is a conservative measure of the problem", as many shootings with fewer fatalities occur.[5][6] The crowdsourced Mass Shooting Tracker project has the most expansive definition of four or more shot in any incident, including the perpetrator in the victim inclusion criteria.[7]
There were 614 mass shootings in 2020 that fit the inclusion criteria of this article, resulting in 446 deaths and 2,515 injuries, for a total of 2,961 victims. Compared to the previous year, there were 180 more incidents. However, according to Statista the number is only 2 for 2020 compared to 10 mass shootings in 2019.[8]
There is no broadly agreed-to, specific conceptualization of this issue, so this report uses its own definition for public mass shootings.
...'mass shooting' is a term without a universally-accepted definition.
